TII's Lightning Surge Protector greatly increases subscriber premise reliability and reduces consumer electronic equipment failures. These failures are caused by induced HIGH VOLTAGE surges that appear on the center conductor of coaxial drop cables within the home. The protector's unique IN-LINE design and 75 ohm impedence matching is virtually transparent to all analog or digital bi-directional signals utilized in the bandpass of DC to 1.5Ghz.

TII's patented proprietary coaxial gas tube surge protector is equipped with an intergral failshort mechanism for a power-cross condition. The DC breakdown voltage of the protector is low enough to protect against even the smallest transient surges, yet causes no conflicts with VoIP network powered applications.

The metallic housing of the TII IN-LINE Coaxial Lightning Surge Protector provides adequate EMI shielding. It also is environmentally sealed to prevent ingress of moisture and humidity that has been shown to introduce CPD to a subscriber's premise drop.
